Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An apparatus comprising: at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: search for feasible component carriers by measuring interference on selected component carriers, and in response to finding at least one feasible component carrier whose interference is below a set threshold according to Quality of Service requirements, take it into use; in response to finding more than one feasible component carrier, take one of the feasible component carriers into use and include the others into a backup list; select at least one home node for carrying out negotiations for obtaining at least one feasible component carrier, the selection being based on the measurements, and carry out negotiations between the selected node and a neighboring home node for obtaining at least one feasible component carrier, in response to failure to find any feasible component carriers in the search, wherein negotiations for obtaining at least one feasible component carrier comprise a request to release a feasible component carrier currently in use so as to make that component carrier available for the at least one home node; in response to obtaining at least one feasible component carrier based on the negotiations, take into use the at least one feasible component carrier; and in response to failure to obtain any feasible component carriers, take into use the component carrier experiencing the lowest interference.
The apparatus selects a communication channel ("component carrier") based on interference. It measures interference on various component carriers. If it finds a carrier with interference below a Quality of Service threshold, it uses it. If multiple carriers meet this threshold, one is used and the others are saved as backup options. If no suitable carrier is found, the apparatus negotiates with nearby nodes to request a release of a currently used, but feasible, carrier. If negotiation is successful, the released carrier is used. If all else fails, the carrier with the absolute lowest interference is used.
2. The apparatus of claim 1 , further caused to: receive a backup list from at least one home node comprising information on at least one of: one or more feasible component carriers which are not in use, and one or more mapping relationships between the one or more feasible component carriers which are not in use and one or more feasible component carriers which are in use.
The apparatus described for selecting a communication channel also receives a list of backup component carriers from other nodes. This list includes information about feasible component carriers that are currently unused, and/or mapping relationships between currently used and unused feasible component carriers. This allows the apparatus to consider alternatives suggested by other nodes, increasing the chances of finding a suitable channel.
3. The apparatus of claim 1 , further caused to: find on the received at least one backup list a component carrier which is feasible if released from use; transmit to the at least one home node a component carrier reselection request to change the component carrier in use to one of component carriers on the at least one backup list, and receive a message on the component carrier change.
The apparatus, already described for selecting a communication channel, further utilizes backup lists. It searches received backup lists for a component carrier that would be suitable if it were released. If found, the apparatus sends a request to the home node using that component carrier, asking it to switch to a different carrier on the backup list. Upon successful component carrier change, the apparatus receives a confirmation message.
4. The apparatus of claim 1 , further caused to: measure interference on the feasible component carrier; and take the feasible component carrier into use.
The apparatus, described for selecting a communication channel, also measures interference on a feasible component carrier before using it. This measurement confirms that the component carrier is still acceptable before switching to it and commencing use. It adds an extra verification step to ensure acceptable Quality of Service.
5. The apparatus of claim 1 , further caused to: update a backup list with information on at least one of the following: one or more feasible component carriers which are not in use, and one or more mapping relationships between the one or more feasible component carriers which are not in use and one or more feasible component carriers which are in use.
The apparatus, described for selecting a communication channel, updates a backup list with information on available component carriers. This information includes a list of feasible component carriers that are currently unused, and/or mapping relationships between currently used and unused feasible component carriers. This facilitates the sharing of resource information between nodes.
6. The apparatus of claim 1 , the apparatus comprising a node device.
The apparatus, already described for selecting a communication channel, is a node device. This clarifies that the carrier selection and negotiation processes are performed within network nodes themselves to optimize network resources.
7. A method comprising: searching for feasible component carriers by measuring interference on selected component carriers, and in response to finding at least one feasible component carrier whose interference is below a set threshold according to Quality of Service requirements, taking it into use; in response to finding more than one feasible component carrier, taking one of the feasible component carriers into use and including the others into a backup list; in response to failure to find any feasible component carriers: selecting at least one home node for negotiations for obtaining at least one feasible component carrier, the selection being based on the measurements, carrying out negotiations between the selected home node and a neighboring home node for obtaining at least one feasible component carrier, in response to failure to find any feasible component carriers in the search, wherein negotiations for obtaining at least one feasible component carrier comprise a request to release a feasible component carrier currently in use so as to make that component carrier available for the at least one home node, in response to obtaining at least one feasible component carrier based on the negotiations, taking into use the at least one feasible component carrier, and in response to failure to obtain any feasible component carriers, taking into use the component carrier experiencing the lowest interference.
The method involves selecting a communication channel ("component carrier") based on interference. The process measures interference on various component carriers. If a carrier with interference below a Quality of Service threshold is found, it's used. If multiple carriers are suitable, one is used, and the others are saved as backup options. If no suitable carrier is found, the method negotiates with nearby nodes to request release of a currently used feasible carrier. If negotiation is successful, the released carrier is then used. If negotiation fails, the carrier with the lowest interference is used.
8. The method of claim 7 , further comprising: receiving a backup list from at least one home node comprising information on at least one of: one or more feasible component carriers which are not in use, and one or more mapping relationships between the one or more feasible component carriers which are not in use and one or more feasible component carriers which are in use.
The method for selecting a communication channel also includes receiving a backup list of component carriers from other nodes. This list includes info about feasible carriers that are currently unused, and/or mapping relationships between currently used and unused feasible component carriers. This helps to find a suitable channel by considering the component carriers suggested by other nodes.
9. The method of claim 7 , further comprising: finding on the received at least one backup list a component carrier which is feasible if released from use; transmitting to the at least one home node a component carrier reselection request to change the component carrier in use to one of component carriers on the at least one backup list, and receiving a message on component carrier change.
The method, already described for selecting a communication channel, further utilizes backup lists. It searches received backup lists for a component carrier that is feasible if released. If such a carrier is found, a request is sent to the home node using that carrier, asking it to switch to a different carrier on the backup list. A message is received upon successful component carrier change, confirming the carrier transition.
10. The method of claim 7 , further comprising: measuring interference on the feasible component carrier; and taking the feasible component carrier into use.
The method, described for selecting a communication channel, also measures interference on a feasible component carrier before switching to it. This step helps verify that the feasible component carrier has acceptable Quality of Service. Finally, the feasible component carrier is taken into use.

The method of claim 7 , further comprising: updating a backup list with information on at least one of: one or more feasible component carriers which are not in use, and one or more mapping relationships between the one or more feasible component carriers which are not in use and one or more feasible component carriers which are in use.
The method, described for selecting a communication channel, also updates a backup list with information on available component carriers. This information includes unused feasible carriers, and/or mappings between used and unused carriers. This keeps an updated view of available and switchable resources, aiding in more informed decision-making.

An apparatus comprising: means for searching for feasible component carriers by measuring interference on selected component carriers, and in response to finding at least one feasible component carrier whose interference is below a set threshold according to Quality of Service requirements, taking it into use; means for, in response to finding more than one feasible component carrier, taking one of the feasible component carriers into use and include the others into a backup list; means for selecting at least one home node for negotiations for obtaining at least one feasible component carrier, the selection being based on the measurements, and carrying out negotiations between the selected node and a neighboring home node for obtaining at least one feasible component carrier, in response to failure to find any feasible component carriers in the search, wherein negotiations for obtaining at least one feasible component carrier comprise a request to release a feasible component carrier currently in use so as to make that component carrier available for the at least one home node; means for, in response to obtaining at least one feasible component carrier based on the negotiations, taking into use the at least one feasible component carrier; and means for, in response to failure to obtain any feasible component carriers, taking into use at least one component carrier experiencing the lowest interference.
This is an apparatus that performs selecting a communication channel ("component carrier") based on interference using "means for" each step. The device measures interference on various component carriers. If it finds a carrier with interference below a Quality of Service threshold, it uses it. If multiple carriers are suitable, one is used, and the others are saved as backup options. If no suitable carrier is found, the device negotiates with nearby nodes using "means for" each negotiation step to request the release of a currently used feasible carrier. If the negotiation is successful, the apparatus uses the released carrier. If negotiation fails, the device uses the carrier with the lowest interference.

A non-transitory computer readable medium storing a program of instructions, execution of which by at least one processor configures an apparatus to perform at least: searching for feasible component carriers by measuring interference on selected component carriers, and in response to finding at least one feasible component carrier whose interference is below a set threshold according to Quality of Service requirements, taking it into use; in response to finding more than one feasible component carrier, take one of the feasible component carriers into use and including the others into a backup list; in response to failure to find any feasible component carriers: selecting at least one home node for negotiations for obtaining at least one feasible component carrier, the selection being based on the measurements, carrying out negotiations between the selected node and a neighboring home node for obtaining at least one feasible component carrier in the search, wherein negotiations for obtaining at least one feasible component carrier comprise a request to release a feasible component carrier currently in use so as to make that component carrier available for the at least one home node, in response to obtaining at least one feasible component carrier based on the negotiations, taking into use the at least one feasible component carrier, and in response to failure to obtain any feasible component carriers, taking into use at least one component carrier experiencing the lowest interference.
A non-transitory computer-readable medium stores instructions that, when executed, cause an apparatus to select a communication channel ("component carrier") based on interference. This involves measuring interference on various component carriers. If a carrier with interference below a Quality of Service threshold is found, it is used. If multiple carriers are found, one is taken into use and the others are included into a backup list. If no suitable carrier is found, negotiations with nearby nodes occur to request the release of a currently used feasible carrier. If negotiation is successful, the released carrier is used. If negotiation fails, the carrier with the lowest interference is used.
